Results From 2004 to 2014,totally 215 368 person?times were examined, and the positive rate of the blood examinations of the population was 0.24%(478/198 356),and there were no positive cases de?tected out by using the miracidium hatching method. Totally 11 935 domestic animals were detected and no positives were found. From 2004 to 2014,the total area with snails was 92.27 hm2,and marshland,inland and mountain environments accounted for 34.75%,34.82%and 30.43%,respectively. The newly discovered area with snails was 34.40 hm2,and marshland,inland and mountain environments accounted for 2.62%,71.22% and 26.16%,respectively. Totally 8 511 snails were dissected and no schistosome infected snails were found. From 2004 to 2014,a total of 242 600 harmless toilets were built,2 704 700 domestic animals were reared in pens,5.82 km?long rivers were dredged,2 250.11 hm2 of protective forests were constructed,a total area of 625.79 hm2 were controlled with molluscicides,and an area of 149.58 hm2 were environmentally transformed.
